Description

Sodium 5-[[4-(acetylamino)phenyl]azo]salicylate is an organic compound that exhibits various color changes when interacting with different chemicals. It is characterized by its deep green light yellow color and is soluble in water, displaying a yellow to red light yellow hue. It is slightly soluble in ethanol and acetone. When mixed with concentrated sulfuric acid, it turns golden yellow, and upon dilution, it becomes a shallow orange color. In concentrated nitric acid, it forms an orange solution. When its dye aqueous solution is mixed with concentrated hydrochloric acid, it turns brown light olive and precipitates. The addition of concentrated sodium hydroxide solution results in a golden orange color.

Check Digit Verification of cas no

The CAS Registry Mumber 6408-39-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,0 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6408-39:
(6*6)+(5*4)+(4*0)+(3*8)+(2*3)+(1*9)=95
95 % 10 = 5
So 6408-39-5 is a valid CAS Registry Number.
